Description

Technical Field

[0001] The present application relates to the technical field of juice production, and in particular to a multi-layer permeation filtration device for juice beverages. Background Art

[0002] In the production process of fruit juice beverages, filtration is a key link, and its purpose is to remove impurities in the juice and improve the purity and taste of the juice. At present, the existing juice filtration equipment has problems such as unsatisfactory filtration effect, low filtration efficiency, easy clogging, and difficult cleaning. At the same time, as people's requirements for the quality of fruit juice beverages continue to increase, a more efficient and reliable filtration equipment is needed to meet market demand.

[0003] For example, a juice clarification and filtering device for juice production with publication number CN118698220A, through the arrangement of the filter cartridge and the rotating and lifting components, can first pour the juice into the filter cartridge for filtering, and under the action of the rotating and lifting components, can drive the filter cartridge to rotate, and under the action of centrifugal force, can throw out the residual juice in the pulp, so that the filtering effect is better and the filtering speed is faster. After the filtering is completed, the rotating and lifting components drive the bottom plate to descend and cooperate with the water spray cleaning component to quickly rinse and discharge the residual pulp, which is more convenient to use.

[0004] However, the above-mentioned prior art still has some defects when filtering juice: 1. The above-mentioned patent application has only one filtration step when filtering juice, and the viscosity, density and pulp particle size of different types of juices are different. Therefore, when there is only one filtration step when filtering different types of juices, the filtration effect will inevitably vary due to the different characteristics of different types of juices, which will lead to unstable juice filtration effect and reduce the juice filtration efficiency.

[0005] 2. In the above patent application, when the water spray pipe flushes the filter cartridge from the outside, due to the limited number of water spray pipes, the sprayed water flow cannot completely cover the circumference of the filter cartridge, which will cause the residual pulp on the filter cartridge to be unable to be completely washed away, that is, the filter cartridge cannot be cleaned. Therefore, when the juice is filtered next time, the residual pulp will contaminate the juice, thereby affecting the quality of the juice.

[0006] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for juice filtration. Summary of the invention

[0039] The following is combined with Figures 1 to 10 This application is described in further detail.

[0040] The embodiment of the present application discloses a multi-layer osmotic filtration device for fruit juice beverages. By adopting three layers of filter screens, the pore size of each layer of filter screens decreases successively, which can effectively filter out the pulp and other impurities in the juice, thereby significantly reducing the impurity content in the juice and significantly improving the quality of the juice.

[0041] Embodiment 1:

[0042] Reference Figure 1 and Figure 2 A multi-layer permeation filtration device for juice beverages includes a cartridge shell 1, a feed hopper 11 is installed on the top of the cartridge shell 1, and a first filtering mechanism 2, a second filtering mechanism 3 and a third filtering mechanism 4 are sequentially arranged inside the cartridge shell 1 along its height direction from top to bottom.

[0043] Reference Figure 2 and Figure 3The first filtering mechanism 2 includes a rotating telescopic rod 21, which is rotatably arranged on the top of the cylinder shell. A rotating rod 24 is rotatably installed on the bottom of the rotating telescopic rod 21 through a bearing. A plurality of rotating shafts 25 are evenly rotated and installed on the outer wall of the bottom of the rotating rod 24 along its radial direction. Fan-shaped blades 26 are installed on the rotating shaft 25. A first water spray cleaning component 22 is installed on the top of the cylinder shell 1, and a first filter screen 23 is installed on the inner wall of the cylinder shell 1 below the rotating rod 24.

[0044] Reference Figure 6 The second filtering mechanism 3 includes a second water spray cleaning component 32, which is installed on the inner wall of the cartridge shell 1 and is located below the first filter screen 23. A toothed disc ring 31 is rotatably installed on the top of the second water spray cleaning component 32, and a plurality of stirring rods 34 are evenly installed at the bottom of the toothed disc ring 31. A stirring blade 35 is installed at the bottom of the stirring rod 34 to stir the juice to speed up the filtration speed. A second filter screen 33 is installed on the inner wall of the cartridge shell 1 below the stirring blade 35.

[0045] Reference Fig. 9 The third filtering mechanism 4 includes a filtering drum 41 , which is mounted at the bottom of the cartridge shell. A third water spray cleaning assembly 42 is mounted on the inner side wall of the cartridge shell 1 corresponding to the filtering drum 41 .

[0046] Among them, before the filtration starts, all valves are in a closed state. During the specific implementation process, the juice raw material is poured into the cylinder shell 1 from the feed hopper 11, and the telescopic rod 21 is rotated under external drive (not shown in the figure) to start rotating and drive the rotating shaft 25 to rotate. At this time, the fan-shaped blades 26 are in an inclined state and rotate with the rotating shaft 25, so that the fan-shaped blades 26 can stir the juice raw material. Stirring can break up some larger pulp agglomerates and break up these pulp agglomerates into smaller particles, so that the smaller particles can pass through the first filter screen 23 more easily without clogging it, thereby improving the filtration efficiency; at the same time, when the juice is filtered, continuous stirring can make the solid impurities evenly distributed on the surface of the first filter screen 23 to avoid clogging; in addition, the slight flow generated by stirring can help the juice to be filtered faster, thereby reducing the filtration time and improving the filtration efficiency.

[0047] Since the pulp of the juice raw material filtered in the first filtering mechanism 2 may be large, it may take a long time to stir it alone. At this time, stop the external drive and turn the fan-shaped blades 26 from the inclined state to the straight state, and the fan-shaped blades 26 are combined into a complete circular plate. Start the telescopic function of the rotating telescopic rod 21. The rotating telescopic rod 21 can carry the combined fan-shaped blades 26 to perform squeezing and lifting movements. When the fan-shaped blades 26 are squeezed downward, pressure can be applied to the solid part of the juice raw material such as pulp, pomace, etc., to promote the juice therein to flow out faster, thereby accelerating the filtering process. At the same time, the pulp cells of many fruits contain a large amount of juice. The structure of the pulp cells can be destroyed by squeezing, so that the juice in the cells can be released, thereby increasing the juice yield.

[0048] After the first filtering mechanism 2 completes the preliminary filtration of the juice raw materials, the initially filtered juice enters the second filtering mechanism 3, and after the juice completely enters the second filtering mechanism 3, the first water spray cleaning component 22 is started to clean the first filtering mechanism 2, and the residual pulp is discharged and collected to facilitate the next filtration without interference.

[0049] Among them, the aperture 33 of the second filter net is smaller than the aperture of the first filter net 23, so the second filter mechanism 3 can filter some smaller pulp and improve the quality of the juice. The toothed ring 31 in the second filter mechanism 3 starts to rotate under the drive and rotates with the stirring rod 34 and the stirring blade 35, and then the stirring blade 35 stirs the juice in the second filter mechanism 3, thereby accelerating the filtration speed and improving the filtration efficiency. After the juice in the second filter mechanism 3 is filtered, the juice enters the third filter mechanism 4. At the same time, the second water spray cleaning component 32 is started to clean the second filter mechanism 3, and the residual pulp is discharged and collected to facilitate the next filtration without interference.

[0050] Among them, the aperture of the filter drum 41 is smaller than the aperture of the second filter screen 33, so when facing different types of juice, three filters of different specifications can ensure that the juice is filtered cleanly, reducing the filtration cost while improving the quality of the juice. The filter drum 41 starts to rotate under the drive, and under the centrifugal effect, the pulp and juice begin to separate. After the pulp and juice are completely separated, the juice finally filtered is collected, and the third water spray cleaning component 42 is started to clean the third filter mechanism 4, and the residual pulp is discharged and collected to facilitate the next filtration without interference.

[0051] Reference Figure 3 and Figure 4In order to enable the fan-shaped blades 26 to change from a straight state to an inclined state as the rotating telescopic rod 21 rotates, a pull rope 27 is commonly provided between one side of one end of each fan-shaped blade 26 close to the inner wall of the cylinder shell 1 and the rotating telescopic rod 21, and a limiting rod 28 is installed at the bottom of the fan-shaped blade 26 on the side of the pull rope 27 of the rotating rod 24 to limit the rotating fan-shaped blade 26 to ensure that the fan-shaped blade 26 can form a straight state, and a torsion spring 29 can be commonly installed between the rotating rod 24 and the fan-shaped blade 26.

[0052] During the specific implementation process, under external drive, the rotating telescopic rod 21 starts to rotate and rotates with the pull rope 27. Under the pulling force of the pull rope 27, the fan-shaped blades 26 are tilted and rotate with the rotating rod 24, thereby starting to stir the juice, thereby improving the juice yield and filtration efficiency; when the filtration rate of the juice is not significantly improved, the external drive is reversed, and the rotating telescopic rod 21 drives the pull rope 27 to reverse, and the pull rope 27 is relaxed. At this time, the external drive stops, and under the action of the torsion spring 29, the fan-shaped blades 26 start to rotate, and stop rotating after contacting the limit rod 28, so that the fan-shaped blades 26 return to a straight state, and all the fan-shaped blades 26 in the straight state are combined to form a circular plate. At this time, the telescopic function of the rotating telescopic rod 21 is started, and the circular plate can squeeze the juice, thereby accelerating the filtration speed and improving the filtration efficiency.

[0053] Reference Figure 2 and Figure 5 In order to prevent the pulp particles from clogging the first filter screen 23, the first water spray cleaning component 22 includes a plurality of first water spray vertical pipes 221 penetrating the top of the cylinder shell 1 to clean the inner wall of the cylinder shell 1. The first water spray vertical pipes 221 are evenly distributed in the cylinder shell 1 along the circumference of the cylinder shell 1, and the top of the first water spray vertical pipes 221 is a water delivery end.

[0054] A plurality of spray heads are evenly installed on one side of the first water spray vertical pipe 221 close to the inner wall of the cylinder shell 1, and a first water spray ring pipe 222 is installed between the first water spray vertical pipes 221 through connecting rods along the radial direction of the cylinder shell 1 to clean the first filter screen 23, and a plurality of spray heads are also evenly installed on the bottom of the first water spray ring pipe 222.

[0055] During the specific implementation process, after the filtration is completed, the first water spray vertical pipe 221 and the first water spray ring pipe 222 spray high-pressure water to the inner wall of the cylinder shell 1 and the first filter net 23 corresponding to the first filter mechanism 2, so as to clean the residual pulp on the inner wall of the cylinder shell 1 and the first filter net 23 and discharge it from the cylinder shell 1 for collection and utilization, so as to avoid pulp accumulation that reduces the speed of the next filtration, thereby reducing the filtration efficiency.

[0056] Reference Figure 2 and Fig.10In order to discharge the pulp remaining on the first filter screen 23 out of the cylinder shell 1 , a first discharge pipe 210 is provided on the inner wall of one side of the cylinder shell 1 corresponding to the first filter screen 23 , and a first discharge valve 211 is provided on the first discharge pipe 210 .

[0057] A first liquid outlet 212 is formed at the lower end of the first filter screen 23 , and a first liquid outlet valve 213 is installed on the first liquid outlet 212 .

[0058] Among them, before the filtration begins, all valves are in a closed state. During the specific implementation process, when the first filter mechanism 2 is filtering, the first liquid outlet valve 213 is opened, and the juice filtered through the first filter screen 23 enters the second filter mechanism 3. After the filtration is completed, the first liquid outlet valve 213 is closed and the first discharge valve 211 is opened. At the same time, the first water spray cleaning component 22 is started to clean the first filter mechanism 2, and the fan-shaped blades 26 are rotated in an inclined state, which can not only scrape off the pulp attached to the first filter screen 23, but also speed up the water flow rate, thereby speeding up the cleaning efficiency. Under the action of the water flow, the pulp is discharged from the cylinder shell 1 through the first discharge pipe 210 and collected. After all the pulp is discharged from the cylinder shell 1, the first discharge valve 211 is closed.

[0059] Reference Figure 6 and Figure 7 In order to enable the stirring blade 35 to rotate and thus stir the juice, a plurality of support rods 36 are evenly arranged on the outer surface of the cartridge shell 1 corresponding to the second filtering mechanism 3, and a support ring 37 is installed between the support rods 36 and the outer surface of the cartridge shell 1, and a driving motor 38 is fixed to the support ring 37 by bolts.

[0060] The driving end of the driving motor 38 is inserted into the cylinder shell 1 and is provided with a driving bevel gear 39 meshing with the gear ring 31 .

[0061] Among them, since the aperture of the second filter 33 is smaller than the aperture of the first filter 23, the second filter mechanism 3 can further filter the juice, thereby improving the quality of the juice. In the specific implementation process, the drive motor 38 is started. At this time, the driving end of the drive motor 38 drives the driving bevel gear 39 to rotate, and the driving bevel gear 39 drives the gear ring 31 to rotate through the meshing transmission, and then the gear ring 31 drives the stirring rod 34 and the stirring blade 35 to rotate, and stirs and filters the juice in the second filter mechanism 3, which can break some larger pulp so that it can pass through the second filter 33. At the same time, the pulp attached to the surface of the second filter 33 can also be stirred to prevent blockage from affecting the filtering effect, thereby accelerating the filtering speed and improving the filtering efficiency.

[0062] Reference Figure 8In order to prevent the pulp particles from clogging the second filter screen 33, the second water spray cleaning assembly 32 includes a water storage ring 321, and a plurality of fixing rods are installed between the water storage ring 321 and the inner wall of the cylinder shell 1, and the water storage ring 321 is rotatably connected to the gear ring 31 through a bearing.

[0063] A water inlet pipe 322 penetrating through the cylinder shell 1 is installed on one side of the water storage ring 321 close to the inner wall of the cylinder shell 1 .

[0064] A plurality of second water spraying vertical pipes 323 are evenly installed at the bottom of the water storage ring 321 to clean the inner wall of the cylinder shell 1 corresponding to the second filtering mechanism 3 . A plurality of spray heads are also evenly installed on one side of the second water spraying vertical pipe 323 close to the inner wall of the cylinder shell 1 .

[0065] A second water spray ring pipe 324 is commonly installed at the bottom of the second water spray vertical pipe 323, and a plurality of spray heads are also evenly installed at the bottom of the second water spray ring pipe 324.

[0066] Among them, the stirring blade 35 will not interfere with the second water spray cleaning component 32 during operation. During the specific implementation process, after the second filtering mechanism 3 completes the filtering, the second water spray cleaning component 32 is started, and the cleaning water flows into the water storage ring 321 from the water inlet pipe 322 and enters the second water spray vertical pipe 323 and the second water spray ring pipe 324 from the water storage ring 321. The second water spray vertical pipe 323 and the second water spray ring pipe 324 clean and discharge the pulp remaining on the inner wall of the cylinder shell 1 and the second filter net 33, and collect and utilize the discharged pulp at the same time, thereby avoiding pulp accumulation and reducing the speed of the next filtration, thereby reducing the filtration efficiency.

[0067] Reference Figure 2 and Fig.10 In order to discharge the pulp remaining on the second filter screen 33 out of the cartridge shell 1 , a second discharge pipe 310 is provided on the inner wall of one side of the cartridge shell 1 corresponding to the second filter screen 33 , and a second discharge valve 311 is provided on the second discharge pipe 310 .

[0068] A second liquid outlet 312 is formed at the lower end of the second filter screen 33 , and a second liquid outlet valve 313 is installed on the second liquid outlet 312 .

[0069] Among them, before the filtration starts, all valves are in a closed state. During the specific implementation process, when the second filtering mechanism 3 is filtering, the second liquid outlet valve 313 is opened, and the juice filtered by the second filter screen 33 enters the third filtering mechanism 4. After the filtration is completed, the second liquid outlet valve 313 is closed and the second discharge valve 311 is opened. At the same time, the second water spray cleaning component 32 is started to clean the second filtering mechanism 3, and the stirring blade 35 is rotated, which can not only scrape off the pulp attached to the first filter screen 23, but also speed up the water flow rate, thereby speeding up the cleaning efficiency. Under the action of the water flow, the pulp is discharged from the barrel shell 1 through the second discharge pipe 310 and collected. In addition, the residual cleaning water in the first filtering mechanism 2 can be discharged into the second filtering mechanism 3 when the second filtering mechanism 3 is cleaning, and discharged from the barrel shell 1 together with the pulp. After the pulp is completely discharged from the barrel shell 1, the second discharge valve 311 is closed.

[0070] Embodiment 2:

[0071] Reference Figure 2 , Fig. 9 as well as Fig.10 In order to enable the filter drum 41 to rotate and thus achieve a filtering effect, a rotating motor 43 is installed at the bottom of the cartridge shell 1 , and a driving end of the rotating motor 43 is connected to the bottom of the filter drum 41 .

[0072] The third filtering mechanism 4 also includes a driving cavity 44, which is arranged between the bottom of the cartridge shell 1 and the filter drum 41, and the rotating motor 43 is located in the driving cavity 44.

[0073] A third discharge pipe 48 is provided between the bottom of the filter drum 41 and the drum shell 1 , and a third discharge valve 49 is provided on the third discharge pipe 48 .

[0074] Among them, since the aperture of the filter drum 41 is smaller than the aperture of the second filter net 33, the filter drum 41 can further filter the juice and thus improve the quality of the juice. During the specific implementation process, the rotating motor 43 is started, and the filter drum 41 begins to rotate with the juice. Under the centrifugal effect, the pulp and the juice begin to separate, the pulp is intercepted by the filter drum 41, and the juice is thrown out of the filter drum 41 and enters the filtrate cavity 45 for collection. After the filtration is completed, the rotating motor 43 is turned off, and at the same time, the valve of the third liquid outlet 46 is opened, and the final juice is discharged from the cartridge shell 1 through the third liquid outlet 46 and collected.

[0075] In addition, the third discharge valve 49 is opened to discharge the pulp in the filter drum 41 from the third discharge pipe 48 and collect it.

[0076] Reference Fig. 9 In order to clean the filter drum 41 that has completed filtration and prevent the pulp from clogging the filter drum 41 and thus affecting the filtration effect, the third water spray cleaning assembly 42 includes a third water spray ring pipe 421, and a plurality of support blocks are installed between the side of the third water spray ring pipe 421 close to the inner wall of the cylinder shell 1 and the inner wall of the cylinder shell 1.

A plurality of spray heads are also evenly arranged on one side of the third water spray vertical pipe 423 close to the filter drum 41 .

[0080] During the specific implementation process, after the juice in the filtrate cavity 45 is discharged through the third liquid outlet 46, the third liquid outlet valve 47 is closed, and the third water spray cleaning assembly 32 is started to clean the filter drum 41, and the filter drum 41 is rotated, so that the third water spray vertical pipe 423, the third water spray ring pipe 421 and the fourth water spray ring pipe 424 can realize all-round cleaning of the filter drum 41. In addition, the remaining cleaning water in the second filter mechanism 3 can be discharged into the third filter mechanism 4 when the third filter mechanism 4 is cleaning, and then the pulp inside the filter drum 41 can be flushed, and discharged from the cartridge shell 1 together with the pulp from the third discharge pipe 48. In addition, the water flow thrown into the filtrate cavity 45 by the filter drum 41 can also clean the inner wall of the filtrate cavity 45, and finally discharged from the third liquid outlet 46. After all the pulp is discharged from the cartridge shell 1, the third discharge valve 49 and the third liquid outlet valve 47 are closed.

[0081] The implementation principle of the present invention is:

[0082] (1): Pour the juice raw material from the feed hopper 11 into the cylinder shell 1, and rotate the telescopic rod 21 under external drive (not shown in the figure) to start rotating and drive the rotating shaft 25 to rotate. At this time, the fan-shaped blades 26 are in an inclined state and rotate together with the rotating shaft 25, so that the fan-shaped blades 26 can stir the juice raw material. When the pulp of the juice raw material is large, stop the external drive and turn the fan-shaped blades 26 from the inclined state to the straight state. The fan-shaped blades 26 are combined into a complete circular plate, and the telescopic function of the rotating telescopic rod 21 is started. When the fan-shaped blades 26 are squeezed downward, they can exert pressure on the solid part of the juice raw material such as pulp, pomace, etc., so that the juice therein flows out faster, thereby accelerating the filtering process.

[0083] (2): The toothed ring 31 in the second filtering mechanism 3 starts to rotate under the drive and rotates with the stirring rod 34 and the stirring blade 35, and then the stirring blade 35 stirs the juice in the second filtering mechanism 3, thereby accelerating the filtration speed and improving the filtration efficiency. After the juice in the second mechanism is filtered, the juice enters the third filtering mechanism 4. At the same time, the second water spray cleaning component 32 is started to clean the second filtering mechanism 3, and the residual pulp is discharged and collected.

[0084] (3): The filter drum 41 starts to rotate under the drive, and under the centrifugal effect, the pulp and juice begin to separate. After the pulp and juice are completely separated, the juice finally filtered is collected, and at the same time, the third water spray cleaning component 42 is started to clean the third filter mechanism 4, and the remaining pulp is discharged and collected to facilitate the next filtration without interference.
